C#设计模式之Facade外观模式解决天河城购物问题示例
本篇章节讲解C#设计模式之Facade外观模式解决天河城购物问题。分享给大家供大家参考,具体如下: 一、理论定义 外观模式 把 分散的子系统,集合成一个系统,提供一站式服务。 二、应用举例 需求描述: 聂小倩 和 宁采臣是一对小富则安 的聊斋夫妻。住在比较偏远的小乡村。 三、具体编码 1.阿迪达斯 using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Com.Design.Gof.Facade { /// <summary> /// 阿迪达斯 /// </summary> public class Adidas { public void Serivce(string something) { Console.WriteLine("在阿迪达斯购买了: "+something); } } } 2.飞扬影城 using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Com.Design.Gof.Facade { /// <summary> /// 飞扬影城 /// </summary> public class FeiYangMovie { public void Serivce(string something) { Console.WriteLine("在飞扬影城看了一部电影: " + something); } } } 3.国美电器 using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Com.Design.Gof.Facade { /// <summary> /// 国美电器 /// </summary> public class GoMe { public void Serivce(string something) { Console.WriteLine("在国美电器 买了: " + something); } } } 4.哈根达斯 using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Com.Design.Gof.Facade { /// <summary> /// 哈根达斯 /// </summary> public class HaagenDaz { public void Serivce(string something) { Console.WriteLine("在哈根达斯 买了: " + something); } } } 5.真功夫 using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Com.Design.Gof.Facade { /// <summary> /// 真功夫 /// </summary> public class KungFu { public void Serivce(string something) { Console.WriteLine("在真功夫 吃了: " + something); } } } 6.六福珠宝 using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Com.Design.Gof.Facade { /// <summary> /// 六福珠宝 /// </summary> public class LukFook { public void Serivce(string something) { Console.WriteLine("在六福珠宝 买了: " + something); } } } 7.耐克 using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Com.Design.Gof.Facade { /// <summary> /// 耐克 /// </summary> public class NIKE { public void Serivce(string something) { Console.WriteLine("在耐克店 买了: " + something); } } } 8.ONLY using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Com.Design.Gof.Facade { /// <summary> /// ONLY时装 /// </summary> public class ONLY { public void Serivce(string something) { Console.WriteLine("在ONLY时装 买了: " + something); } } } 9.苏宁电器 using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Com.Design.Gof.Facade { /// <summary> /// 苏宁电器 /// </summary> public class Suning { public void Serivce(string something) { Console.WriteLine("在苏宁电器 买了: " + something); } } } 10.Veromoda国际时装品牌 using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Com.Design.Gof.Facade { /// <summary> /// Veromoda国际时装品牌 /// </summary> public class Veromoda { public void Serivce(string something) { Console.WriteLine(something); } } } 11.消费者 using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Com.Design.Gof.Facade { /// <summary> /// 消费店子 /// </summary> public enum ShopOption { Adidas = 1,DKNY = 2,GoMe = 3,NIKE = 4,Suning = 5,Veromoda = 6,FeiYangMovie = 7,HaagenDaz = 8,LukFook = 9,KungFu = 10 } /// <summary> /// 消费单 /// </summary> public class Bill { /// <summary> /// 要去的消费店 /// </summary> public ShopOption Item { get; set; } /// <summary> /// 去这个店要买啥 /// </summary> public string Something { get; set; } } public class Consumer { /// <summary> /// 消费单 /// </summary> public IList<Bill> Items { get; set; } /// <summary> /// 姓名 /// </summary> public string Name { get; set; } } } 12.天河城---一站式服务 using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Reflection; namespace Com.Design.Gof.Facade { /// <summary> /// 天河城 /// </summary> public class TeeMall { private static readonly Assembly assembly = Assembly.LoadFile(AppDomain.CurrentDomain.BaseDirectory + @"Com.Design.Gof.dll"); /// <summary> /// 一站式服务 /// </summary> /// <param name="consumer"></param> public void OfferService(Consumer consumer) { Console.WriteLine("我是: " + consumer.Name+",不差钱,今天来天河城玩: "); Console.WriteLine("----------------------------------------------"); foreach (Bill item in consumer.Items) { object obj= assembly.CreateInstance("Com.Design.Gof.Facade." + item.Item); MethodInfo info = obj.GetType().GetMethod("Serivce"); info.Invoke(obj,new object[] { item.Something }); } Console.WriteLine(); } } } 13.主函数调用 using System; using System.Collections.Generic; using System.Linq; using System.Text; using Com.Design.Gof.Facade; namespace Com.Design.Gof.Test { class Program { static void Main(string[] args) { //天河城购物中心 TeeMall TeeMall = new TeeMall(); //消费者 1 Consumer consumer = new Consumer { Name="聂小倩",//消费单 Items = new List<Bill> { new Bill{ Item=ShopOption.Adidas,Something="运动服"},new Bill{ Item=ShopOption.GoMe,Something="苹果IPhone智能手机"},new Bill{ Item=ShopOption.FeiYangMovie,Something="<冰河世纪 4>"},new Bill{ Item=ShopOption.KungFu,Something="香菇炖鸡"},new Bill{ Item=ShopOption.LukFook,Something="金项链"},} }; TeeMall.OfferService(consumer); //消费者 2 consumer = new Consumer { Name = "宁采臣",//消费单 Items = new List<Bill> { new Bill{ Item=ShopOption.FeiYangMovie,Something="《太空一号》"},new Bill{ Item=ShopOption.Veromoda,Something="然后去了Veromoda时装,买了一套服装"},new Bill{ Item=ShopOption.HaagenDaz,Something="买了一雪糕"},new Bill{ Item=ShopOption.Suning,Something="在苏宁看买平板电脑"},} }; TeeMall.OfferService(consumer); Console.ReadKey(); } } } 14.运行结果 15.总结 天河城 TeeMall 理论上应该包括 所有 商场的引用, 这里用反射 避免了这一动作。 附:完整实例代码点击此处本站下载。 更多关于C#相关内容还可查看本站专题:《C#数据结构与算法教程》、《C#窗体操作技巧汇总》、《C#常见控件用法教程》、《WinForm控件用法总结》、《C#数组操作技巧总结》及《C#面向对象程序设计入门教程》 希望本文所述对大家C#程序设计有所帮助。 (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
